You're riding in an airplane flying at the height of 2 miles above the ground.the distance along the ground from airport is 5 miles.what is the angle of depression from the airplane to the airport

Sagot :

This might be what it looks like.

Since we're dealing with an angle, its opposite side and it's adjacent side, we use TANGENT.

[tex]tan(angle)= \frac{opposite}{adjacent} [/tex]

opposite=5
adjacent=2

By taking the angle, we use inverse.
[tex]angle= tan^{-1} \frac{5}{2} [/tex]

Then we can finally know the value by using your calculator. :)
